Boxplot showing median, interquartile range, and full range of day 57/29 Enz and metabolite drug levels by dose escalation cohort. The Enz drug level trough drug concentration (Ctrough) achieved equivalent PK levels at a dosing of Enz 120 mg, Mif 300 mg with ratio of 1.0 for cohort 3, which became the recommended phase 2 dose. “X” denotes mean within each group.
Abbreviations: Ctrough, concentration of Enz and metabolite on given day; Enz, enzalutamide; Mif, mifepristone.
